This application is a national stage entry of International ApplicationNo. PCT/FR2008/051975, filed on Oct. 31, 2008, which claims priority toFrench Application No. FR 0758744, filed Oct. 31, 2007.

The present invention provides a method of lightening and/or colouringhuman keratin fibres using, on the one hand, a composition comprising aspecific aminosilicon compound and, on the other hand, an oxidizingcomposition.

It also provides a specific composition comprising a specificaminosilicon compound and at least one fat.

It provides, lastly, a multiple-compartment device in which at least onecompartment comprises the abovementioned composition and at least oneother compartment comprises an oxidizing composition.

The techniques for colouring human keratin fibres such as the hairinclude permanent or oxidation colouring. This means of colouring, moreparticularly, employs one or more oxidation dye precursors, moreparticularly one or more oxidation bases optionally in combination withone or more couplers.

Oxidation bases are typically selected from ortho- orpara-phenylenediamines, ortho- or para-aminophenols, and heterocycliccompounds. These oxidation bases are colourless or weakly colouredcompounds which, in combination with oxidizing products, provide accessto coloured species by a process of oxidative condensation.

The shades obtained with these oxidation bases are very often varied bycombining them with one or more couplers, the latter being selected inparticular from aromatic meta-diamines, meta-aminophenols,meta-diphenols, and certain heterocyclic compounds, such as indolecompounds.

The variety of molecules employed as oxidation bases and couplers allowsa rich palette of colours to be obtained.

The colouring method involves contacting the oxidation dye precursor orprecursors with an oxidizing agent, which is preferably hydrogenperoxide, under alkaline conditions. One of the difficulties lies in thefact that the most commonly used alkaline agent is aqueous ammonia,whose function is to adjust the pH of the composition to an alkaline pHin order to allow the breakdown of the oxidizing agent. Hence the oxygenformed causes condensation of the oxidation dye precursors and alightening of the fibre by virtue of the breakdown of the melaninpresent. The alkalifying agent also has another role, namely that ofswelling the keratin fibre in order to promote the penetration of theoxidizing agent and the dyes to the interior of the fibre.

This alkalifying agent is highly volatile, and this causesunpleasantness to the user on account of the strong and fairlyunpleasant odour of the ammonia which is given off during the procedure.

Moreover, the amount of ammonia given off requires the use of levelswhich are greater than those necessary, in order to compensate thisloss. This is not without consequence for the user, who not only remainsdiscomforted by the odour but may also be confronted with greater risksof intolerance, such as, for example, irritation of the scalp (stingingsensations).

The option purely and simply of replacing all or some of the aqueousammonia by one or more other conventional alkalifying agents does notresult in compositions which are as effective as those based on aqueousammonia, particularly for the reason that these alkalifying agents donot provide sufficient lightening of the pigmented fibres in thepresence of the oxidizing agent.

Another colouring technique employed is that of direct or semi-permanentcolouring. This procedure involves applying direct dyes to the keratinfibres, said dyes being coloured and colouring molecules which have anaffinity for the fibres, and then leaving them to take, to allow themolecules to penetrate by diffusion to the interior of the fibre, andthen rinsing the fibres.

The direct dyes generally employed are selected from nitrobenzene,anthraquinonoid, nitropyridine, azo, methine, azomethine, xanthene,acridine, azine or triarylmethane direct dyes.

This colouring technique does not require the use of an oxidizing agentunless the desire is to lighten the fibre at the same time as colouringit. In the latter case, the procedure is as for oxidation dyeing, inother words contacting the keratin fibres with the dyeing composition inthe presence of an oxidizing agent, more particularly hydrogen peroxide,under alkaline conditions, generally in the presence of aqueous ammonia.The user, consequently, is then confronted once again with the samedifficulties as those set out before for oxidation dyeing.

Further to the colouring procedures, it is likewise common to employlightening procedures in which the keratin fibres are contacted with anoxidizing composition under alkaline conditions. These procedures onlyinvolve breaking down the melanin in the hair, to a greater or lesserextent depending on the oxidizing agent selected. Thus a peroxygenatedsalt leads, generally speaking, to more pronounced lightening than whenusing hydrogen peroxide alone under alkaline conditions. Irrespective ofthe oxidizing agent employed, however, the lightening procedures requirethe use of hydrogen peroxide under alkaline conditions, and moreparticularly in the presence of aqueous ammonia, to form or acceleratethe formation of oxygen. Consequently, once again, the same difficultiesare encountered as those with the colouring procedures employed in thepresence of an oxidizing agent and aqueous ammonia.

One of the objectives of the present invention is therefore to providecolouring and/or lightening compositions for human keratin fibres thatare intended for use in the presence of an oxidizing agent but which donot exhibit the same disadvantages as the existing compositions, owingto the presence of large amounts of aqueous ammonia, while remaining atleast equally effective, from the standpoints both of lightening and ofcolouring, and which display, more particularly, high performance interms of chromaticity, power and homogeneity.

It should be noted that it was far from being obvious to employ aminosilicon compounds corresponding to those of the formula (I) asalkalifying agents in this type of method.

The reason is that, in the presence of sufficient amounts of water, themajority of these amino silicon compounds rapidly undergo hydrolysis andcondensation. The expectation would therefore have been a drop in theeffectiveness of colouring and/or lightening, as a result of poorpenetration of the silicon-based polymers resulting from this reactioninto the fibre on account of their size, diminishing accordingly thelightening power or colouring power of the composition.

These aims and others are achieved by the present invention, whichaccordingly provides a method of colouring and/or lightening humankeratin fibres, in which said fibres are contacted with:

These dyes may be monochromophoric dyes (i.e. comprising only one dye)or polychromophoric, preferably di- or trichromophoric, dyes; thechromophores may be identical or different, and from the same chemicalfamily or otherwise. It should be noted that a polychromophoric dyecomprises two or more radicals each derived from a molecule that absorbsin the visible region between 400 and 800 nm. Furthermore, thisabsorbance of the dye does not require any prior oxidation thereof, orcombination with any other chemical species.

In the case of polychromophoric dyes, the chromophores are connectedtogether by means of at least one linker, which may be cationic ornon-cationic.

The linker is preferably a linear, branched or cyclic C₁-C₂₀ alkyl chainwhich is optionally interrupted by at least one heteroatom (such asnitrogen, oxygen) and/or by at least one group comprising such aheteroatom (CO, SO₂), optionally interrupted by at least one heterocyclewhich is or is not fused with a phenyl nucleus, and comprising at leastone quaternized nitrogen atom which is part of said heterocycle, andoptionally at least one other heteroatom (such as oxygen, nitrogen orsulphur), optionally interrupted by at least one substituted orunsubstituted naphthyl or phenyl group, optionally at least onequaternary ammonium group which is substituted by two optionallysubstituted C₁-C₁₅ alkyl groups; the linker does not contain a nitro,nitroso or peroxo group.

If the heterocycles or aromatic nuclei are substituted, they aresubstituted, for example, by one or more C₁-C₈ alkyl radicals which areoptionally substituted by a hydroxyl group, C₁-C₂ alkoxy, C₂-C₄hydroxyalkoxy, acetylamino, amino substituted by one or two C₁-C₄ alkylradicals, which optionally carry at least one hydroxyl group, or the tworadicals may, with the nitrogen atom to which they are attached, form a5- or 6-membered heterocycle, optionally comprising another heteroatomidentical to or different from nitrogen; a halogen atom; a hydroxylgroup; a C₁-C₂ alkoxy radical; a C₂-C₄ hydroxyalkoxy radical; an aminoradical; an amino radical substituted by one or two identical ordifferent C₁-C₄ alkyl radicals which optionally carry at least onehydroxyl group.
